A tool worth having in your 'occasional' box is a hand held impact driver.
You can find these hand tools as sets with various bits supplied. These
are strong persuaders for stuck screws. My old Triumph motorcycle almost
demanded one be used often.
This tool is a screw driver-like device with a big fat steel handle you
can smack with a hammer ("Impact" dri...?) and the blow not only supplies
force directly "down" the tool into the head of the screw, allen, torks,
whatever..but it also translates into a sharp turning force. I've never had
one of these tools apart to see exactly how it works, but I surmise it has
some kind of 'ramp' and spring innards and you 'pre-turn' the body of the
device to 'load up' the potential force, then when you smack it with the
hammer, it forces the bit to try to turn the fastener while the hit drives
it down into the 'recess' of the fastener head to help pervent 'camming
out".
